mysql，发现都是乱码，一堆问号，如下图：
查看mysql编码
需要修改mysql编码，打开/etc/my.cnf 文件
在下边添加如下行
[client] default_character_set=utf8 [mysqld] collation_server = utf8_general_ci character_set_server = utf8
修改后的/etc/my.cnf如下：
[mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid [client] default_character_set=utf8 [mysqld] collation_server = utf8_general_ci character_set_server = utf8
再查看如下
已经修改过来了，重启， 再继续查询，能正常显示中文汉字，搞定。
